Genera and Sjiecies of Culeoptera. 17 



tlie scutellum; scutoUum .small, ovate; elytra parallel, ratlier wider 

 than the base of the prothorax, to which they are closely approximate, 

 each with five very marked elevated lines, the wide excavated grooves 

 between these impuuctate, but with a faint trace of another line ; body 

 beneath dark chestnut ; le<;s reddish chestnut ; femora very robust ; 

 tibiiu short, subtrigonal, spurred, the anterior very strongly curved ; 

 tai*si elongate, the basal larger than the two following, especially the 

 intermediate and posterior. Length 3^ lines. 



Penthelispa [Colydiidce].

Penthelispa Truquii. 



P. fusco-castanea, subnitida ; prothorace convexo, fortiter punctato, late- 

 ribus antice rotundatis, medio pauUo constrictis. 



Hah. Mexico. 



Chestnut-brown, the elytra sometimes with a more reddish tint than 

 the rest, j^^ibnitid ; head coarsely punctured ; antennae rather stout, the 

 last joint of the club somewhat narrower than the preceding one ; pro- 

 thorax rather longer than broad, the anterior angles produced, the 

 sides rounded anteriorly, but a little constricted in the middle, then 

 again slightly rounded and contracting to the base, the disk convex, 

 without any central depression, and veiy coarsely punctured j scutellum 

 transversely rounded; elytra broadest nearly at the base, and very 

 slightly rounded at the sides for two-thirds its length, the anterior 

 angle not produced, strongly striato-punctate, the punctures shortly 

 linear; body beneath dark chestnut-brown, shining, very coarsely 

 punctured ; legs dark brown. Length 2 lines. 



There is a great similarity between the various species of Penthe- 

 llspa*, but the i)rothorax appears to offer good characters by which 

 they may be distinguished. The one described above has that part 

 regularly convex, and free from any impression or any elevated line, 

 and this separates it from the remainder of the few species yet pub- 

 lished. I owe my specimens to my kind friend Mr. Fry, who re- 

 ceived it together with a vast number of Colcoptera collected in 

 Mexico by the late lamented Signore Truqiii, the Italian Minister in 

 that country, after whom I have named it. 



Ipsaphes [Cucujidoe]. 



Caput obcordatum, angulis posticis baud productis, coUo brevissimo. 

 Antennce moniliformes, articulo primo brevi, tertio paidlo longiore. 



* This name was pubUshed in October 1860. Dr. Leconte, in his ' Classifi- 

 cation of the Colcoptera of North America,' published at Washington " May 

 1861 — March 1862," proposed the term '' Endedus" for the North American 

 species.
